3Brown1Blue recently posted an excellent video on how he's thinking about AI's impact on math, which of course is in a similar position as programming. One of the points he made was that machines' abilities to lift heavy things has no bearing on the value of exercise -- which is to say that, just because AI can now code/do math extremely well, that has no bearing on the positive effects (the "mental exercise") one gets from programming/doing math "the old way;" the same can be said about one's enjoyment.
The problem here, though, is that I used to get the enjoyment/"exercise"/upskilling/etc from the same 8 hours that paid for my life. Now, I have to squeeze that in _outside_ of those 8 hours. So AI has, very clearly and simply, reduced my downtime outside of work -- I literally have less time for non-programming hobbies and activities because of AI.
